What is Azure?
Windows Azure Virtual Machines enable organizations to create and manage their SharePoint infrastructure quickly— provisioning and accessing nearly any host universally. It allows full control and management over processors, RAM, CPU ranges, and other resources of SharePoint virtual machines (VMs).
Windows Azure Virtual Machines mitigate the need for hardware, so organizations can turn attention from handling high upfront cost and complexity to building and managing infrastructure at scale. This means that they can innovate, experiment, and iterate in hours, as opposed to days and weeks with traditional deployments.
